WALTER KELLNER, OF BARMEN-WICHLINGHAUSEN, GERMANY, ASSIGNOR TO CARL F. .AHLSTROM AND OTTO J. AHLSTROM, BOTH OF NEW YORK, N. Y.

Application filed August 9, 1912.

To all whom it may concern:

Be it known that I, WALTER Knnnnnn, of vViescherstr-asse 13, Barmen-Vichlinghausen. Rhenish Prussia, (,iermany, a subject of the Emperor of Germany, have invented new and useful Improvements in and Relating to Braiding-Machines, of which the following is a specification.

This invention relates to braiding machines and particularly to a novel device to be used in connection with such machines for-the purpose of temporarily locking the bobbins at predetermined points in their travel. Such devices, after temporarily holding the bobbin, project the bobbin again into contact with parts of the mechanism to enable the bobbins to be again advanced. The movements of the bobbins are usually controlled by a pattern mechanism.

The primary object of this invention is to provide a simple device comprising a locking means at each station where the bobbin stops for'lo-cking said bobbin against movement, a reciprocating means adjacent each locking means for projecting the bobbin. into the guide track after being unlocked, and means actuated by the pattern mechanism for imparting the desired operations to the locking means and the projecting means for placing in action, a bobbin hitherto inactive.

In the accompanying drawings, Figure 1 is a vertical sectional view of so much of the braiding machine as is necessary to show the operation of the improved device which is applied thereto. Fig. 2 is a plan view of the same. Fig. 3 is a detail view of the locking means.

Referring to Figs. 1, 2 and 3, the numeral 1 indicates the top plate of a braiding machine in which the intersecting guide tracks 4 are formed. A short distance below the top plate is an under plate 2, pillars 3 connecting the two plates and serving as axes about which the drivers for moving the bob bins 5 and their gearing revolve. The drivers and gearing being well known are omitted from the drawings. At the intersections of the guide tracks 4 are stations 6 where the bobbins Sbeing disengaged from the drivers pause in their travel. These stations are formed by cutting away the plate 1 at each intersection of the tracks 4 and on opposite sides thereof. Opposite each station is aswitch 4 of the usual type for directing the movement of the bobbins.

Serial No. 714,190.

Mounted on the under plate 2 adjoining each station (5 and on the same side of the track intersection as said station is a bearing 9 through which passes a pivot pin 8 serving as a fulcrum for a lever arm 9 held upward in operative position by a spring 19. The free end of the lever arm 9 is preferably widened to form a head 10 in which is made a central hole or recess 12, the upper face of said head on each side of the hole being curved or inclined as at 11, Fig. 3. Into the hole or recess 12 the lower end of a bobbin 5 enters when arrested at a station and is locked against accidental movement.

Against the under side of the top plate 1 above each lever arm 9 is an ejecting means such as a reciprocating slide 17, movable in a guide 17 across the station 6 into the intersection of the tracks 4. The slide lies normally under the plate 1, its active end being close to the bobbin 5, or the space to be occupied by said bobbin when at rest. A stop 18 is secured to the plate 1 back of each slide to limit its retractive movement.

Pivoted on the pin 8 beside the locking lever 9 is an angle lever 18, 14, the arm 13 thereof projecting upwardly from the pivot 8 and having a round head 13 neatly engaging with a socket 17 in the slide 17. The other arm 14 extends in a horizontal direction beside the locking lever and bears at its free end on a pin 15 projecting from the side of the locking lever. A lug 16 on the underside of the arm 14 is perforated for a connection with the pattern mechanism. A spring 20 connected to the arm 13 of the angle lever and to a pin fixed in the plate 1, holds the slide 17 and angle lever in retracted position.

A bobbin 5 moved along the track by the drivers will become disengaged therefrom when it reaches an intersection and enter one of the stations 6, in doing so its lower end engages the face 11 of the head 10 of the locking lever and this depresses said lever until the bobbin 5 lies above the 'hole or socket 12, when the lever is drawn back by the spring 19, and the bobbin enters hole 12 and is locked against movement. The depression of lever 9 does not disturb the angle lever 13,14, the pin 15 swinging away from the arm 14, and hence the bobbin becomes locked without actuating the ejecting means. When the pattern mechanism draws down on the angle lever, the latter positively depresses the locking lever and frees the bobbin which is then pushed by the slide 17 out of the station 6 into the intersection of the tracks 4 Where it is caught by one of the adjacent drivers and moved onward or retracted, the direction being controlled by the position of the. switch 4* opposite the station. The springs 19, 20 then return the levers to their normal positions. As the arm 13 moves the slide the head 13 rises or falls in the socket 17 of the slide.

What I claim is:

1. In a braiding machine in combination, a bobbin movable along a track arranged to stop at determined stations out of the path of travel, ejecting means at each station for projecting the bobbin into the path of travel, a bell crank lever mounted so as to actuate said means, and a movable arm connected to an arm of said lever and having a seat for engaging the end of the bobbin to lock the same, said last named arm movable independently of said ejecting means to permit said seat to engage the bobbin.

2. In a braiding machine in combination, a bobbin movable along a track and arranged to stop at determined stations out of the path of travel, ejecting means at each station for projecting the bobbin into the path of travel, a bell crank lever to actuate said means and locking means for engaging the end of the bobbin and independently movable with respect to said bell crank lever to permit the same to lock the bobbin Without actuating said ejecting means.

3. In a braiding machine in combination, a bobbin movable along a track arranged to stop at determined stations out of the path of travel, means at each station for projecting a bobbin into the path of travel, a bell crank lever arranged to actuate said means and a locking arm arranged to swing down wardlv independently of said bell crank lever, to engage a bobbin and lock the same, and means for actuating said locking lever when said bell crank lever is actuated to release the bobbin.

4. In a braiding machine, a bobbin movable along a track and adapted to stop at determined stations therein out of the path of travel, a lever at each of said stations depressible by said bobbin for locking the same against movement, a reciprocating slide also at each of said stations for projecting the bobbin into the path of travel, and an automatically operated angle lever one arm of which contacts with and depresses the locking lever to disengage the bobbin, and the other arm actuates the slide to forward said bobbin into the path of travel.

5. In a braiding machine in combination, a bobbin movable along a track arranged to stop at determined stations out of the path of travel, means at each station for projecting a bobbin into the path of travel, a bell crank lever arranged to actuate said means and a locking arm arranged to swing downwardly independently of said bell crank lever to engage a bobbin and lock the same, and means for actuating said locking lever when said bell crank lever is actuated to release the bobbin, said locking lever having a seat for engaging the lower end of the bobbin When locking the same, said seat having an inclined face in the path of the bobbin adapted to move said locking lever independently of said bell crank lever in locking the bobbin.

6. In a braiding machine in combination, a bobbin movable on a track arranged to stop at determined stations out of the path of travel, a slide at each station for project ing a bobbin into the path of travel, a bell crank lever having an upwardly extending arm with a rounded head thereupon, said slide having a socket receiving said head, said bell crank lever having a substantially horizontal arm, means connected with said bell crank lever and movable independently thereof to lock the bobbin Without actuating said slide, and mounted so as to be actuated when said bell crank lever is moved in a direction to advance said slide to project the bobbin into the path of travel.

7. In a braiding machine, a bobbin movable along a track arranged to stop at deter mined stations thereon out of the path of travel, a lever at each of said stations depressible by said bobbin for locking the same against movement, said lever having a socket therein and an inclined face adjacent to said socket adapted to be engaged by the bobbin to depress the lever and engage the bobbin by the said socket in said lever, a reciprocating slide also at each sta tion for projecting the bobbin into the path of travel and an automatically operated angle lever one arm of which contacts with and depresses the locking lever to disengage the bobbin, the other arm being arranged to actuate the slide to advance the bobbin into the path of travel.
